Fixing setup and hold violations
WebMar 3, 2024 · Setup and Hold Times . The simulator will issue a setup or hold time violation any time data changes at a register input (data or clock enable) within the setup or hold time window for the particular register. There are a few typical causes of a setup or hold time violation: - The path to this register was not constrained. WebDec 9, 2024 · Ways to solve setup time violation The fundamental idea behind solving setup violation is to make the data path logic quicker. If that doesn’t work, then making the clock path logic slower will also help solve the timing problem.
